· Mg4Sc3(SiO3)8

Mg₄Sc₃(SiO₃)₈ is a magnesium-scandium silicate ceramic compound that combines magnesium and scandium oxides with silicate structure, representing an advanced silicate ceramic in the rare-earth-doped ceramic family. This material is primarily of research and development interest rather than established production use, with potential applications in high-temperature structural ceramics, thermal barrier coatings, and optical applications where the addition of scandium is known to enhance thermal stability and mechanical properties compared to conventional magnesium silicates. Its appeal lies in scandium's ability to increase melting point, reduce thermal expansion mismatch, and improve creep resistance—making it a candidate for aerospace thermal management and next-generation refractory applications where conventional silicates fall short.

Regulatory Screening

Environmental

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
